What it is
A soothing bark that coats and protects irritated digestive and throat surfaces. Traditional use for acid reflux, IBS, and sore throat spans centuries. No human trials exist, and all evidence is based on historical use and theoretical support. Generally well tolerated. Take 2 hours away from medications because it may slow their absorption.
